peeps at the cutting point, at which
happily connects. A typical thank you move, since White has not accomplished anything while in return Black's major aji has disappeared.
White should cut at in this diagram. Now the group at the bottom does not have a base and is under attack; and
can cause trouble later in the game.
Compare the two diagrams. This one is obviously better for White.

aLegendWai: Sometimes a peep at the cutting point is okay. It is because you simply cannot cut (or will not cut in the future). A peep may act as some blockage for B to invade.
aLegendWai: My idea though. A cutting point seems to mean a point where a separation of stones will take place if it is placed by enemy stones. It may not be a effective cut or the cut may not be succeed. I still hear commentaries, books say something like this cutting point cannot be cut!.
Alex Weldon: See the /discussion page for my take on this.
A peep may be used to destroy eyespace. See Peep to reduce eyespace for details.
